Sammendrag

This report presents an evaluation of initial heat pump concepts and integration principles for SHIP200. Two main concepts have been developed: a high-temperature concept based on water/steam (R718) for short term heat delivery up to 200°C and a reversed Brayton heat pump concept based on CO2 (R-744) for long-term heat delivery up to 250°C. Evaluations of different heat pump concepts, component and system TRL level and cost have been performed. Both heat pump concepts were modelled in Modelica for detailed investigation of both design and off-design (part load) operational performance and stability in order to assess operability and integrability of the heat pump. The steam heat pump achieved a COP of 4.97 at design conditions, while the reversed Brayton cycle heat pump achieved a COP of 2.44. Model improvements to both concepts can be made to improve simulation accuracy and performance.
